An odor collecting pipe for exhaust gas and an odor gas storage cabinet (9) are connected to an air pump (10). The air pump (10) is connected to an odor gas inlet (103) of the rapid decomposition device (1), and a clean gas exhaust pipe (104) is connected at one end of the clean gas organization chamber (8), as shown in FIG. 6 of the drawings.

In particular, organic or foul odor gas subject to deodorization treatment are collected to the odor gas storage cabinet 9 through the odor collecting pipe for exhaust gas and drawn through an air pump to enter into the multifunctional microwave plasma and ultraviolet light deodorization treatment unit of the present invention. Then, the odor gas are guided to flow sequentially to the rapid decomposition device (1), the high frequency plasma electric field (2), the microwave plasma electric field (3), the high intensity ultraviolet radiation field (4), the low temperature plasma electric field (5), the high intensity ozone gas reaction chamber (6), the reaction termination chamber (7) and the clean gas organization chamber (8), thereby the odor gas is treated by multifunctional microwave plasma and ultraviolet light deodorization treatment unit of the present invention to form a discharge gas and the discharge gas is discharged to the natural air. The discharge gas is colorless, odorless and sterilized, which is fresh and safe to the environment.

The rapid decomposition device (1) comprises activated carbon (12) for adsorption function and a monofluoro atom oxide catalyst (14), wherein the monofluoro atom oxide catalyst is commercially available under the trade name sodium monofluorophosphate, and the chemical formula is Na2PO3F. The activated carbon is arranged to adsorb large particles of gas molecules to filtering gas molecules less than 10,000 mesh. The rapid decomposition device (1) also has an ultraviolet radiation emission arrangement for providing ultraviolet radiation. After ultraviolet radiation, strong decomposition process occurs in the presence of the catalyst and the activated carbon such that the odor gas molecules are reorganized into carbon-, oxygen-, and hydrogenated-containing substances and the odor level is greatly reduced.

The activated carbon plays the role of physical decomposition. The principle is: rapid filtering of gas molecules less than 10,000 mesh and adsorption of large gas particles; after ultraviolet radiation, the catalyst provides a function of chemical decomposition.

The high-frequency plasma generated by the high-frequency plasma electric field generator carries out an adaptive oxidation treatment to odor material and the odor material is further oxidized and reduced. When a new oxide is formed from the transformant, this deep treatment creates conditions for structural damage to achieve further deodorization.

In the plasma region, the odor and the bacteria attached to the dust undergo ionization breakdown and chain reaction through the high-frequency plasma electric field, so the dust having a size above 0.5 μm is adsorbed, and reactions to organic matter and bacteria are initiated, the reactions are as follows:

O3 and OH− react together to produce O2− and HO2;

Free radical chain reactions are as follows:

O3 and O2− react together to produce O3− and O2;

HO3− react to produce O3− and H;

HO3− react to produce OH and O2;

H2R and OH− react to produce HR− and H2O;

3O3R, 2OH− and H+ react to produce 2OH− and 4O2;
